It's one of the worst RTS games ever made, and I was genuinely surprised when they said that Ensemble had anything to do with it. Kind of strange that the people who made Age of Empires would suddenly create the RTS equivalent of Tickle-Me-Elmo. It's a kid's game, but what do you expect? People who play Halo installments are not the typical RTS target market, so of course it's going to be watered down and have minimal depth compared to real titles of that genre.
I'm sure they made a boatload of money on it though, if that's what you're asking.
